To ctZZ whom it may concern: v

Be it known that we, WILLIAM BELL caster, England, subjects of the Kingof Great Britain, have invented certain new and us'e" ful Improvementsin and Relating to the Winding of Tarps or Threads, of which thefollowing is a specification.

This invention relates to certain improvements in guides4 for winding#frames and guides for expanding spring-combs for beaming and tape sizingmachines and also to means for applying additional tension or drag tothe yarn prior to passing through our improved guide. l

As is well known, the usual guide for winding-frames takes the shape ofa flat steel plate with slits cut init at intervals for the twist topass through. In its passage through these slits the twist is constantlyrubbing against the sharp edges of the plate for the purpose of cleaningit, it is said; but the twist or yarn thus treated is impaired in itsstrength, often breaks near the guide-plate, and causes an undueaccumulation of fiuihwhich sometimes escapes or passes through the slitsof the guide and when sized in the taping-machine is formed into hardlumps. These pass on to the weavers beam and appear again in the processof weaving, causing breakage of ends and a waste of time. Dilerentcounts of twist are wound on the same winding-framefine counts andcoarse counts. In winding iine counts the Winder-guide often allows thelumps or snarls or fluff which come up or accumulate to pass through themachine,which, as before stated, occasions a lot of trouble to theweaver` in the shape of ends breaking down. As a substitute for theseguide-plates and also for the brushes cards or illet-s or snarI-catchershave been secured to the lifting-rail of the winding-frame, consistingof rows of teeth disposed one behind another, the said teeth beingpushed through a leather strip secured to the lifting-rail and the rowsof teeth being so disposed as to serve the purpose of cleaning the yarnpassing through them and intercepting the passage ofsnarls, fluff, ordirt, as previously described. This arrangement, however, is defectivefrom the point of View that the friction put upon the yarn by the rowsof teeth is very considerable, causing breakages and accumulation offlul between the teeth of the cards.

In the present invention we employ a spiral spring or springs to takethe place of the ordinary guide. These springs may always present asmooth round surface to the twist, and by ameohanical means the coils ofthe springs may be opened or closed, as desired, according to the countsof varn it is intended to clean. The yarn is passed through the coils ofthe springs, which, being smooth, will not inj ure,while at the sametime efiiciently cleaning the yarn or twist of snai-ls, fluff, or dirt.Again, we place glass rods inside the spiral spring for the twist toride upon, and so reduce the friction.

By our invention it will be seen that the twist retains its strength orbody after being submitted to the cleaning process, the'friction putupon it being much reduced and the formation of lumps gotten rid of. p

Our spiral-sprin g guide may be adj ustablee'. e., capable of expansionor contraction by any suitable means-or it may be unadjustable. In thelatter caso the spiral springs may be mounted in a trough at a suitabledistance apart, the ends of the springs being secured to the trough byscrews or like means, while the edges of the trough may be formed smoothto allow the yarn to pass over them without injury, or the edges of thetrough may be provided with steel or glass rods, suitably secured to thetrough, for insuring the safe traverse of the yarn.

Our spiral-spring guidesmay be expanded or contracted by-mountin g themin the trough, as before described, and securingtheir respective ends totapped blocks or slides, through which a right and left hand screwed rodor shaft is passed, its right-hand thread engaging with the tapped holein the other block. The screw is mounted in fixed supports or bearingson the trough and provided with a handle or crank when supplied for abeaming or tape-sizing machine, by which the springs may be expanded orcontracted to any degree required.

IOO

In conjunction with our invention glass or p steel tension-hooks may befixed to the kneeboard or to the said trough to give additional tensionto the yarn in cases Where it may be required. These glass or steeltension-hooks may be fixed to the knee-board in different forms, so asto dispense with the well-known flannel that covers the knee-board. Suchflannel is used to get drag or tension on the twist or threads passingover the same. The flannel makes fluff,which reduces the strength of thetwist and passes onto the bobbins and when the twist at a later periodis sized in the sizing-machine comes up again in the shape of a numberof ends fast together. When our glass or steel hooks are used to gettension, the half-moon-shaped kneeboard and flannel maybe dispensedwith, if desired, and we employ instead a flat rectangular board, towhich thc tension-hooks may be fixed direct, or they may be mounted onsuitably-formed plates secured to the said board. The tension hooks maybe formed with flanges like a bobbin to guide the twist. Thetension-hooks may be fixed to the said board in different forms. Theymay be in wood; glass, porcelain, or steel or other metal. They may befixtures or they may revolve. If made to revolve, the glass or porcelainguides may be bushed with wood or wooden pegs employed for them torevolve upon. We may only employ one large revolving bobbin for thetension, made with a flat end and a round end, respectively. The flatend when placed on the peg next the board would give more friction ortension. Thus by reversing the bobbin we alter the tension by frictionalcontact of the bobbin with the board, and the board may have flannelwashers for the bobbins to work against. Such tension-bobbins may alsobe made from different weights of wood, light and heavy timber-lightbobbins for light counts and heavy bobbins for coarse counts.

In sizing or beaming frames the beforenamed spring-guide is well adaptedto be used in substitution of the ordinary expanding-comb, and to openor separate the warp before it gets to the split rods we use anadditional spiral spring with open or closed coils, the latterpreferred. This additional spiral-spring opener assists or eases thesplit rods in the work of opening or dividing the warp-threadswhiclrpass between the coils, and are thereby caused to separate. One ormore of these spiral-spring openers may be used in addition to theexpanding spiralspring guide.

Thenumber of split rods hitherto employed in sizing-machines is reducedby the above arrangement. Besides, the warp being eased and the warp-threads being more readily loosened breakages of same are prevented.

The invention further consists of the novel combination and arrangementof parts hereinafter more specificallydescribed,illustrated in theaccompanying drawings, and particularly pointed out in the claimshereunto appended.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, whereinlike characters of reference indicate corresponding parts throughout theseveral views, and in which- Figure l isafrontelevationof ourimprovedspring-guide, partly broken away, with the tensioning device arranged insuitable relation thereto. Fig. 2 is a sectional elevation of the meansfor securing one end of the spring-guide to a fixed support. Fig. 3 is adetail view of one of the tensioning-hooks. Fig. 4 is a detail view of amodified form of tensioning device. Fig. 5 is an end elevation of thespring-guide connected to a tensioning device. Figs. 6 and 7 aresectional detached elevations of modified forms of spring-guide. Figs. 8and 9 are cross-sectional views thereof.

In the accompanying drawings, Fig. l represents our arrangement ofspiral-spring guide in substitution of the usual guideplates and thelike of winding-frames. The spiral spring A is attached at one end to asupport or bearing B, fixed at the end of the lifter-rail C of thewinding-frame. Spiral spring A is attached at its other end to theadjustable slide-bearing D, which is tapped at E to engage with theright-hand screwthread of shaft F, Whose ends are carried by brackets Gand H, respectively. The spiral spring .I is similarlysecured to thefixed support J on the lifter-rail, and at its other end is alsoattached to adjustable slide-bearing K, whose tapped extremity K'engages With the left-hand screw-thread of shaft F. This shaft is madewith a central boss M, formed with a number of holes in it, by whichmeans it may be turned by a tommy-bar to tighten the coils of thespringin one direction and turned in the opposite direction to slackenthe said coils. In this way the coils of the spring are opened or closedto suit varying counts of yarn. The yarn on its way to the bobbinspasses between the coils of the springs, which, being smooth, do notinjure it, while at the same time thoroughly cleaning it of snarls,fluff, and dirt. Any other suitable means may be employed for adjustingthe coils in place of the method shown. The method of securing the endsof the coil-springs to their bearings or supports will be understood byreference to Fig. 2. For this purpose we make use of the flanged bush M,formed with a screw-thread, upon which a few coils of the spring-guideat the ond are screwed to secure the said spring thereto, when the bushM is then placed in the forked bearings B D or K and J', respectively,and the forked portion above the bush crossed by a split pin to hold thebush in place. (See Figs. 5 and 8.)

A spiral spring or springs may be employed for the purpose describedWithout being provided with any means of adjustment, in which ICO IIO

case the spring or springs are constructed to xed stationary supports,such as B and J As seen in Fig. l, we pass through the coil -spring orsprings a glass rod M for the yarn to bear upon and to present a smoothsurface to it. This glass rod is prevented from slipping out at the endby a small swivel piece or spring N, fixed to the flanges of the bush M.(See Fig. 5.) We also provide steel or glass rods O on each side of therail C below the spiral springs to ease the yarn in its passage. Thesesteel rods are mounted at the ends in brackets B D and K and J. As seenin Fig. 9, these steel rods rest in the recesses O of the bridge-piecesO, which are placed at intervals along the lifting-rail C. The latter isformed /\shaped in cross-section, and the bridge-pieces arecorrespondingly formed to fit upon the same, as shown, and secured bythe screw D. The timber of the lifting-rail is also slightly notched toallow the bridgepicces C to bed into it. vBy this means We obtain astraight secure support for the adjustable spring-guide to rest upon,which is very important, while the ridge shape of the top edge ofthelifting-rail facilitates the clearance of the fluff and dirt.

Our invention has also reference to a tensional appliance or appliancesto be fixed to the knee-board or aboard or plate used in substitutionthereof, the said tension all appliance or appliances serving the samepurpose as the knee-board, but far more efficiently and with lessin jury to the yarn or twist. The said tensional appliances may take diversforms and may be made of glass, wood, porcelain, or any other suitablematerial or metal. They may be fixtures or they may revolve. When theyare fixtures, they may consist of a number of glass 'or steel hooks orpegs, as shown in Fig. 3, and the yarn passed around each of them on itspassage from the cops to the bobbins. The knee-board or the like may bedispensed with altogether and metal plates P fixed at intervals in frontof the windingframe. (See Fig. 4.) We fix or screw into the said platepegs or pins P', on which we mountJ loose bowls yof suitable material N.The yarn from the cop after passing through the notch Q maytraverse overand around a number of these loose bowls or bobbins, by which additionaltension is obtained and by which the degree of tension can be varied byaltering the number of bowls around which the yarn is passed or changingthe position of the yarn on them.

In another method (seen in Figs. l. and 5) pegs R may be xed in aninclined board S, and on such pegs are mounted bobbins T, around whichthe yarn is carried. When fine counts are being Wound, the round end Tof the bobbin may be placed next the board, (see Fig. 5;) but for coarsecounts the bobbins may be reversed and the flat end U put next the boardto increase the friction or drag as the bobbin revolves by bearingagainst the board. Bobbins of dierent weights may also be used for thepurpose of varying the tensiony put upon the yarn. Flannel washers maybe placed on the peg next the bobbin, for the bobbins to work against,and increase th friction if need be.

A slightly-modified form of our spiral-sprin g guide to be used insubstitution of the ordinary expanding-comb for beaming-frames,

sizing-machines, and the like is shown in Figs.

6, 7, and 8.

The ends of the spiral spring 2 are connected to the movable bearings orsupports 3 and 4 and may be secured thereto by the same means aspreviously described and shown in Fig. 2. The coils of the spring 2 areopened or closed by turning the hand-wheel or handle 5, xed to the rightand left hand screw- 4threaded shaft 6, upon which the bearings orsupports 3 and 4 are respectively mounted. The said bearings or supports3 and 4 thus move inwardly or outwardly, according to which directionthe handle is turned, and by this means open and close the coils of thespring.

In addition to our spiral-spring guide .arranged as described to takethe place of the usual expanding-comb We may make an additionalspiral-spring guide to aid the split.

rods in separating or dividing the warpthreads in a tape-sizing machine,whiclrwe cause to pass through the coils of the said additionalspring-guide prior to passing under and over the split rods. By thismeans the number of split rods in comparison to what was formerlyemployed in sizing-machines is reduced, while the warp is eased to someextent in its traverse through the machine, as the Warp-threads aresooner loosened by the coils of the. spring and are not injured as muchthereby, and consequently breakages vare prevented.
